EMS spokesman Stuart Brideaux has said 10 children and four young adults were taken to hospital. One young child was in serious condition, while the rest were stable.

The symptoms were mainly respiratory, said Brideaux.

“Largely these are the typical symptoms we see in any seasonal flu,” he said. “Somebody may have some shortness of breath. They may have a fever. They may be feeling just generally unwell.”

There was no immediate response for comment from either the Alberta government or the office of federal Indigenous Services Minister Jane Philpott.

An official with the Assembly of First Nations said National Chief Perry Bellegarde spoke with Chief Ernest Wesley of the Stoney Nakoda First Nation Wednesday evening but there was no additional information about the incident.
